MACX MCR-EX-SL-IDSI-I(-SP)

Data sheet

1Description

The output isolating amplifier

MACX MCR-EX-SL-IDSI-I(-SP) helps in controlling the

intrinsically safe I/P converters, control valves, and

indicators installed in the Ex area. The device isolates and

transmits 0/4 ... 20 mA signals to the Ex area in an

intrinsically safe manner.

For operating the intrinsically safe SMART actuators, the

analog measuring value can be overlaid with digital

communication signals (SMART/HART) on the Ex or non-Ex

side and transmitted bidirectionally in an electrically isolated

manner.

Test sockets are integrated into the COMBICON connectors

for connecting the HART communicators.

The device has a monitoring unit that checks the device for

wire breaks and it can be installed in zone 2 with the "n"

(EN 60079-15) protection type.
