Mycom CLM 152
FCXI additional module:
Comprising two contact inputs for Hold,
remote measuring range switch-over and
analogue input with measuring transmitter
power supply.
21 Current input, positive
22 Current input, negative
81 Contact input 1
82 Contact input 1
83 Contact input 2
84 Contact input 2
Intrinsically safe ia/ib circuit 1:
Voltage supply
Current drain
Intrinsically safe ia/ib circuit 2:
Voltage supply
Current drain
The parallel switching of the two input circuits is permitted (Tl. 81/82 and
83/84) to power the contact inputs from only one intrinsically safe circuit.
Intrinsically safe ia/ib circuit,
Maximum load 500 Ω
