12V & 24V Coil Voltage Available!
Introduction
The TB-16P8R provides 16 opto-isolated digital inputs and 8 SPDT relay outputs. Each digital input accepts from 3V DC to 24V DC or 6.3mA to 50mA by changing a current limiting resistor. Its opto-isolated inputs provide both isolation between separate channels and between each input channel and your PC system.
On board 8 relay outputs are driven by an 8-bit digital output port. Each relay's switching capacity is 60W/125V AC. The normally closed, normally open and common contacts of each relay are brought out via screw terminals to maximize its flexibility.
Both isolated inputs and relay outputs are equipped with LED's that light up when relays
are energized or input signals are at "High" status.
