Description

Safety related module with 2 x 4-20mA analog inputs and two thresholds to be
programmed on the module through the operator cycle. The following transducer
types can be connected to this module: Explosion Sensors, Air Quality Sensors,
Oxygen Sensors, Temperature Sensors, 4-20mA General Sensors. The channel is
continuously tested during operation. The module features 4-20mA outputs that
provide the current value measured on the input. The analog value of each chan-
nel can be transferred to a DCS by means of the S81-F7006-1 Modbus RTU
module. This module can be duplicated for fault tolerant systems; in this case,
the two modules shall be placed on two adjacent racks in the same position. In
this configuration, the two detection lines are connected to both modules.
