The PC2 timing relay module is intended for AC power status control in object alarm systems (monitoring transmitters, alarm control panels, DC power supply units, etc.). The module informs about AC power loss with a preset delay time and its returne. PC2 has two OC outputs (OC1, OC2) and an LED (L1) indicating the devices status. Delay time indicating AC power loss is adjustable via two jumpers – Z1, Z2. Application: AC power status control : 0÷30V. Power supply: 10÷15VDC. Input: AC1. Output: 2 x OC type - max. 50mA. Time range: 4s / 1min / 16min / 4h15min. Optical indication.
