Universal signal conditioning module, detachable front programming unit 4501, can be configured for all types of standard industrial measuring signals such as RTD, TC, Ohm, potentiometer, mA and V. 2 relays , universal power supply of 21.6 - 253 VAC and 19.2 - 300 VDC
Input for RTD, TC, Ohm, potentiometer, mA and V. 2 adjustable alarm limits. Mounting on DIN rail or wall. 2 relay outputs. Universal AC or DC supply
Advanced features:
• Programmable via detachable display front(4501), process calibration, relay simulation, password protection, error diagnostics andselection of help text in several languages.
Application:
• Process control with 2 pairs of potential-free relay contacts which can be configured to suit any application.
• Trip amplifier with window fonction defined by a high and a low setpoint. The relay changes state outside the window.
• Sophisticated sensor error surveillance, where one relay holds the state immediately prior to the sensor error, thus allowing the process tocontinue. The other relay can be set for sensor error alarm so that the defect sensor can be replaced immediately.
Technical characteristics:
• When 4131 is used with the 4501 display / programming front, all operational parameters can be modified to suit any application. As the 4131 is designed with electronic hardware switches, it is not necessary to open the module for setting of DIP switches.
• A green front LED indicates normal operation and malfunction. A yellow LED is ON for each active output relay.
• Continuous check of vital stored data for safety reasons.
