Add low-cost field I/O (such as a digital I/O module) to your programmable logic controller (PLC)
or PC-based industrial control system
Terminator I/O is 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
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 analog 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
Two sizes of terminal bases accomodate all I/O modules
Half-size bases for up to 8-point modules
Full-size bases for up to 16-point modules
Triple-stack terminal blocks are standard and multi-wire devices are easy to connect
Same bases for all I/O modules - AC, DC, and analog
Network interface modules for your favorite fieldbus
Ethernet - the "common sense network", 10BaseT
DeviceNET, MODBUS and Koyo remote I/O, and Profibus
All network modules include an on-board RS232 serial port, ideal for operator interfaces or other serial
devices (except Profibus modules).
Ethernet modules even support connectivity to bar code readers
Power supplies: freedom of choice, freedom to expand
DC power supplies at affordable prices
AC supplies include 24 VDC auxiliary supply for convenient field device wiring
Need more power for high-current devices or modules? ...
Just add another power supply before the next module in the system!
Discrete I/O with the features you need
8-point or 16-point input and output modules (DC and AC inputs; DC, AC and relay outputs)
8-point 5-36 VDC current sinking/ sourcing isolated output module
All DC input modules are sink/ source jumper configurable
Diagnostic LEDs for blown fuses and 24 VDC power on applicable modules
"Hot-swap" capability makes troubleshooting easy
Analog I/O modules at a low price per channel
8-channel input modules, or choose a 16-channel output module
0-20 mA/ 4-20 mA and unipolar and bipolar voltage models available
14-channel thermocouple input module supports J, E, KE, R, S, T, B, N, and C types
All analog ranges are software configurable - no jumpers required!
"Hot-swap" analog modules for fast system repair
Specialty I/O modules for your industrial control process
Terminator I/O High Speed Counter Module
8 DC sink/ source inputs 9-30 VDC, 4 isolated sink/ source DC outputs, 5-30 VDC, 1 A per point.
2 quadrature encoder counters up to 100 KHz, or 4 single channel counters up to 100 KHz,
and 4 high speed discrete inputs for Reset, Inhibit, or Capture.
4 independently configurable high speed discrete outputs or 2 channels pulse output
control, 20 Hz - 25 KHz per channel, pulse and direction or cw/ ccw pulses. NOTE: (Use with T1K-16B or T1K-16B-1 terminal base.)
Local expansion up to two additional rows!
Full backplane expansion through cables
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
