Contact Specifications

The “contact” closure is provided by a photo-coupled MOS device. Because

it is a solid-state device, it is not subject to arcing and contact-welding as are

mechanical relays. However, since it is a solid-state device, it will be

damaged by operation beyond its ratings, which are:

Nominal Load Voltage: 28 V AC or 48 V DC, Maximum

Peak Voltage: ± 60 V, Maximum

Load Current: ± 1.8 A, continuous Maximum at 77°F (25°C),

derated to 0.7 A at 185°F (85°C)

ON Resistance: 0.12 Ohm, Maximum

Note: Upon power up (powering the console or Envoy), the datalogger will

briefly test all four outputs by closing the circuit (turning on the output). It is

recommended that you disconnect any equipment attached to the datalogger

outputs before rebooting the console or Envoy.
