• I/O module dimensions: 241 x 24.4 x 99.1 mm (H x W x D).
• Total weight: 0.7 kg (main) + 0.4 kg (I/O) = 1.1 kg.

Contact Ratings & Load Capabilities

• Standard relays (silver contacts): minimum switched current 100 mA @ 5 Vdc.
• DC resistive load (max): 5 A switched current; 70 W @ 24 Vdc, 10 W @ 48 Vdc, 9 W @ 60 Vdc.
• Max switched voltage (DC): 125 Vdc; (AC): 250 Vac, 5 A, 1200 VA.
• Failsafe / hazardous area relays: max switched voltage 30 Vdc, current 5 A.
• Low current relays (gold-plated): min 1 mA @ 1 Vdc, max 100 mA @ 48 Vdc.
• For AC up to 120 Vac: minimum switching current 1 mA, maximum before damage 5 mA.
• Important: do not exceed these ratings to prevent relay damage.

Installation & Physical Layout

• Rack space: main module occupies 1 full-height front slot; I/O module uses 1 full-height rear slot.
• Front panel LEDs: OK (green) lights when operating correctly; TX/RX flashes during communication with other 3500 rack modules; CH Alarm illuminates when any relay channel enters alarm state.
• Relay operation groups: four groups of four channels, switch-selectable for Normally De-energized (ND) or Normally Energized (NE).
• Warning: hazardous voltage exists when connecting field wiring – risk of electric shock or burn.
• Explosion hazard: disconnect power before servicing; do not disconnect live circuits in hazardous areas.
