The AHT615-P-RIS is our millivolt input trip amplifier unit suitable for SIL 1, 2 & 3 applications
- Input is any signal within a span of 4 to 400mV
- Trip output is a pair of changeover contacts DPCO, rated at 250Vac, 3A, 100VA (resistive)
- High Trip: Relay de-energise on rising mV OR
Low Trip: Relay de-energise on falling mV.
