Safety is by Choice, Not by Chance.

From |

Phoenix Contact's Safety RelaysAre you selecting a safety relay just to meet the SIL3 requirements?

Who will be responsible for conducting the Proof Test to ensure it is still safety relays are still safe to use?

Which is critical? Safety relays without diagnostics or the Safety relays with diagnostics?

Safety is a Choice, Not by Chance

The graphics below explains the functional principle of the force guided /positive driven contacts in the event of a welded contacts and that’s where the normally closed contacts come into action to provide feedback to inform the system of the failure in relay contacts.

In this case when the relay is de-energized, the normally closed contact cannot close properly having a gap of 0.5mm.

Safety relays for ESD-Emergency Shut-Down Systems should have:

1) Force guided relay enables a feedback path just in case of welded contacts eliminate the need for and simplifies Proof Testing. (ESD-Emergency Shut Down and F&G-Fire & Gas systems)

The diagram below shows connection details for a safety relay used by Fire & Gas Systems. The Fire & Gas System is always on standby mode and it becomes more important to have multiple diagnostics to make sure the Fire and Gas System Safety Relay is still functional and all wirings are connected.

Eliminate Extra Terminal Blocks Using Phoenix Contact’s PLC Relay

Pluggable Compact (PLC) Relay

Pluggable Compact PLC Relay

Is space and cost a concern for you when designing-in relays for automation?

Phoenix Contact’s PLC Relay eliminates the need for extra terminal blocks, helping you reduce both space and cost. Let us see how.

PLC Relay Actuator Series

PLC Relay-Actuator Setup

Relay-Actuator Setup

In applications where only one normally-open(N/O) contact function is required, you can use Phoenix Contact’s PLC to Actuator output relays to interface with actuators, such as motors, contactors or solenoid valves.

You can connect all actuator connections, including the load return line, directly to the relay. Hence, eliminating the need for additional output terminal blocks to transfer power.

The benefit is daisy-chaining or looping the wiring for the power will not be necessary. This is illustrated in the wiring layout below.

Likewise, Phoenix Contact’s PLC to Sensor input relays can be used to interface with sensors, such as proximity switches, limit switches or auxiliary contacts, where only one normally-open(N/O) contact function is required.

Similar to the Actuator Series, you can also connect all sensor connections, including the supply voltage for the sensors/switches.

As you can see, available with screw, spring or push-in field terminals, Phoenix Contact’s relays will:

  • Open up Space on the DIN rail
  • Reduce Labor and components costs
  • Eliminate an extra point of failure

Ultimately, you can save approximately 80 Pecent on your DIN rail and approximately 60 percent less time on installation.

Signal Conditioning – Why we need to isolate, convert, filter and amplify control signal

From |

When dealing with Measurement and Control signals, Signal Conditioners are crucial for the healthy operation of the whole system. Let’s find out why:

  1. Electrical Isolation – The most important task of a signal conditioner is the electrical isolation of signals. A reliable Signal Conditioner offers consistent isolation of input, output, and supply. As such, ground current loops can be prevented in the event of potential differences, which would otherwise lead to a distortion of the measured process values.

  1. Convert – An advantage of signal conversion is the conversion of sensor signals into a signal that can be read by the controller, such as PT100 in 4…20 mA. In addition, failure-prone signals such as 0 – 10 V, for example, can be converted into non-prone current signals.

    MINI Analog Pro converting signals

  1. Amplify – Signals always need to be amplified in the event that cables are long or if high loads are to be driven. It is here where the signal conditioners must provide a high output power at a low input power.

  2. Filter – In industrial environments, interference often occurs as a result of high-frequency signals. The input filters of the signal conditioners therefore reliably filter out such interference signals.

New highly compact isolation amplifiers with UL certification

From |

The Mini Analog Pro product family is the first line of 6-mm isolation amplifiers with plug-in connection technology. There are now four new product types that are UL 508 listed and thus can also be used in the USA and Canada.

4749

The expansion of the product line includes an analog frequency converter with limit value functionality for converting standard signals to frequency or PWM signals, a limit value switch with converter relay output for switching analog limit values, a constant voltage and current source, and a NAMUR insulation amplifier for proximity initiators and voltage-free and resistive switch contacts. The easy-to-configure modules are available with screw-in or push-in connection technology.

The Mini Analog Pro isolation amplifiers can be easily installed and operated in narrow spaces. Easily visible and accessible connection points and power measurements during operation ensure convenient use.

Network-capable hybrid motor starters

From |

The new versions of the Contactron hybrid motor starter from Phoenix Contact enable quick and easy integration into the common fieldbus systems Profibus, Profinet, CANopen®, DeviceNet, Modbus, and EtherNet/IP™.

4732

Process data, such as motor current, is transmitted to the control system via the bus system with the aid of the corresponding gateway. This allows service intervals to be optimized, which plays a role in increasing system availability.

Thanks to the efficient wiring concept of the hybrid motor starter, the new devices also enable easy integration of the fieldbus with a short startup time. Mounting is easy with the DIN rail connector as the devices make contact as they snap on. The control signals are forwarded via the fieldbus system, therefore there is no need for digital outputs for motor control on the controller side. The extensive parallel cabling of the control and signal level is no longer required. All in all, the system offers a compact and economically attractive solution for motor control.

Push-In Technology – Closer than You Think!

From |

Push-In Technology was developed by Phoenix Contact in 1978. The very first modular terminal block, the FK 1,5 with a direct plug-in spring connection, designed to offer installation engineers an easy and safe conductor connection method used this technology.

Due to its handling and compact design, the FK 1,5 is still found in elevator engineering, machine and system construction even today! Just like the FK 1,5, the concept of Push in Technology still exists and is going strong today – because it improves the way we do things…. even in our daily lives!

Read on to find out how.
