Fieldbus I/O

Terminator I/O - the most practical distributed I/O system you can buy.


Terminator I/O provides you with an industrial I/O system with remote I/O, distributed I/O and digital I/O module capabilities. It combines the I/O points with their field terminations into a modular package to save panel space and money. With Terminator I/O, you can use distributed I/O nodes close to field devices for faster and more efficient wiring and troubleshooting.

Terminator I/O was custom-designed for AutomationDirect by Koyo (the same people who designed the original GE Series One PLC), a trusted name in control technology since 1983.
  • Network interface modules supporting Ethernet, Profibus, DeviceNET, MODBUS and Koyo remote I/O;
    some adapters include an on-board RS232 serial port.
  • Discrete and analogue industrial I/O modules with modular terminal bases
  • Configuration flexibility by plugging together a network interface module with up to 16 I/O modules. Use local expansion for large I/O drops. No more confining I/O bases.
  • AC or DC power supplies. For high power systems, combine multiple supplies on a single I/O set.
  • Horizontal or vertical DIN rail mounting

Power supplies / Terminal Bases / CablesPower supplies / Terminal Bases / Cables

AC or DC power supplies. For high power systems, combine multiple supplies on a single I/O set.
Local expansion up to two additional rows! Connect up to 16 modules across three total rows by plugging expansion cable from the right side of one module to the left side of the next - the system automatically recognizes the I/O! Optional cable that includes 24 VDC pins maximizes your power supply capability
Discrete Input modulesDiscrete Input modules

Discrete industrial I/O modules with modular terminal bases. One network interface module accepts up to 16 I/O modules. Use local expansion for large I/O drops. 8/16-point DC and AC input modules sink/ source jumper configurable. "Hot-swap" capability makes troubleshooting easy
Discrete Output modulesDiscrete Output modules

8/16-point DC, AC and relay output modules. 8-point 5-36 VDC current sink/ source isolated output.
LEDs show blown fuses and 24 VDC power on applicable modules. "Hot-swap" capability makes troubleshooting easy
