5.8CONTROL PANEL GPIO EXTERNAL CIRCUITRY

Control panels from the 500-3x-30 and 500-3x-50 range provide 2 local GP inputs and 2 local GP outputs on a D9 fixed socket. The tables in section 8.5.2.2 and 5.5.3 provide pin-out details. The circuit below gives suggested wiring details for Logic Output 1. Like the matrix GPI card (see 3.4.5.2) the maximum current must be limited to 200mA and the maximum external voltage to 200V. Exceeding these limits will damage the panel circuitry.

The circuit below shows suggested wiring for Logic Input 1. If the input circuitry needs to be isolated from the panel voltage, the link between pins 5 and 9 should be removed. An external voltage can now be connected to pin 9 but an additional dropper resistor should be added if this voltage is >5V.
