EOL - PC/104 Module with 8 Changeover Relays and 8 Opto-isolated Inputs
Product phased out. Please call systerra for replacement options.

The AIM104-RELAY8-IN8 is an 8-bit PC/104 module providing eight changeover relays and eight opto-isolated inputs. The board includes jumper options for each digital input to select a 10ms input debounce filter.

Isolation
The module provides up to 1500V electrical isolation between the PC/104 based control system and the electrical system you are controlling. The isolation between adjacent channels is limited to 100V by wiring and connectors.

Relays
The power switching rating for the relay contacts is 60W (resistive load). The relays and board layout are designed to switch voltages up to 220V DC (125V AC), and currents up to 1.0A. However, the Low Voltage Directive specifies that the product can only be safety used up to 48V DC.
