DRAGER 4206078
The REGARD 8-channel display card and 8-input 4-20 module provide:
· Measurement and display of gas level with gas measuring heads
(transmitters) such as Polytron 2. The equipment can be used with
any 4-20mA transmitter.
· Activation of alarms when pre-set gas levels are exceeded.
The input module and display card are intended for permanent
installation in a non- hazardous environment, such as a control
room or marshalling cabinet.
The 8-input 4-20 module takes signals from up to eight 2-wire or
3-wire 4-20mA measuring heads (transmitters). The module provides
terminals for field cables and DC power to the transmitters.
Signals from the eight inputs are multiplexed onto an RS-485
connection for transmission to the 8-channel display card. The
display card displays the gas level of each head and indicates
alarm and fault conditions.
The display card has three alarm relays for
· A1 gas alarm
· A2 gas alarm
· Fault alarm or A3 gas alarm (user-configurable)
Each 8-input module requires an 8-channel display card. Only one
module can be connected to a display card.
The input module and display card can be located in separate
enclosures or buildings. The maximum distance of the RS-485 cable
between the module and display card is 1km.
