The SIMEX SRP-457 is a digital meter in tight (IP 65 or IP 67), wall mounting case, with large 57mm digits, current-voltage input and 1 relay output.
The SRP-457 digital meter is equipped with one measurement input with user selected range 0/4-20 mA and a standard resistor protection circuit or VDC range.
Additionally the SRP-457 allows user to select a conversion characteristic of several kinds: linear, square, square root and user defined – max. 20 points length. Relay output makes it possible to control processes ON/OFF type.
24V DC output to supply a transducer and RS-485 are available in standard version.
The device features a 4-button keyboard for programming basic settings, which for greater security is located under the front cover. In order to make setting changes without unsealing the casing, remote control can be included by means of an (as accessories) infrared remote control unit. The keyboard on this remote control unit operates the same as the device’s keyboard.
