UniStream™ Uni-I/O Modules
Technical Specifications
UID-0808THS
This guide provides specifications for Unitronics’ Uni-I/O™ module UID-0808THS. This module can
be set with up to 2 Shaft Encoders at 250kHz, or up to 2 High Speed PWM at 250kHz and 2 Normal
Speed PWM outputs (1) (2) (3).
Uni-I/O modules are compatible with UniStream™ family of Programmable Logic Controllers. They
may be either snapped onto the back of a UniStream™ HMI Panel next to a CPU-for-Panel to
create an all-in-one HMI + PLC controller, or installed on a standard DIN Rail using a Local
Expansion Kit.
Installation Guides are available in the Unitronics Technical Library at www.unitronics.com

UID-0808THS
Technical Specifications
Notes:
1. The UID-0808THS utilizes two high speed blocks that can each be assigned either to the inputs or
to the outputs.
2. Four inputs may be configured to function either as normal, or as high speed digital inputs, and can
support a total of two shaft encoders.
3. Two outputs are high speed, up to 250kHz, and may function as normal or high-speed PWM
outputs (same frequency and different duty-cycles). Two outputs are normal speed, and may
function as normal-speed PWM outputs (same frequency but different duty-cycles).
4. Inputs I0, I1, I4, and I5 can be configured as either normal digital inputs or as high speed inputs
that can receive high speed pulse signals from sensors or shaft encoders. High speed inputs
specifications apply only when inputs are configured as high speed inputs.
5. Outputs O0 and O1 can be configured as either normal digital outputs or as high speed PWM
outputs. Outputs O4 and O5 can be configured as either normal digital outputs or as normal PWM
outputs. PWM outputs specifications apply only when outputs are configured as PWM outputs.
6. Outputs O0 and O1 share the same frequency but capable of producing different duty-cycles;
Outputs O4 and O5 share the same frequency but capable of producing different duty-cycles.
7. Current consumption does not include load current.
