D5212
- SIL 2 Quadruple Repeater Power Supply
G.M. International ISM0361-3
2
General Description:
The quadruple channel Repeater Power Supply D5212Q provides a fully floating DC supply for energizing conventional 2-wire 0/4-20 mA transmitters located in Hazardous Area, and
repeats the current in Safe Area to drive a load in applications requiring SIL 2 level (according to IEC 61508:2010) in safety related systems for high risk industries.
Function:
4 channels I.S. analog input for 2-wire loop powered transmitters (or separately powered inputs, only for channels 1 and 2), providing isolation between input, output and supply, and
current source output signals. The module is fully configurable to achieve any desired input/output combination: any number of outputs can be independently linked to each input.
Output function can be configured as: adder, subtractor, low/high selector. An optically coupled open-drain alarm output with user-settable trip point is also provided.
Modbus RTU RS-485 output is available on Bus connector to interface digital device.
Configurability:
Totally software configurable (no jumpers or switches), by PC via USB with PPC5092 adapter and related configurator software or by RS485 Modbus output, in order to choose: input
signal range, linear or reverse output signal, alarm trip point, low, high, window or fault repeater alarm mode, hysteresis, delay time.
Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards, in Safe Area or in Zone 2.
