The 1771-OZL is a PLC-5 digital dry-reed relay contact output module. It comes with an 8 Form A or N.O. (normally open) output points that are grouped into 4 sets of 2 outputs, with each group having its own common. These outputs are electrically-isolated from the module's logic circuitry. Eight status indicators on the front plate of the module are available representing the control status of the output relays. Once a relay has been energized, its corresponding indicator will be lit up. It uses a 1771-WD wiring arm and can be installed in a 1771 Series A or B I/O chassis. The entire 1771-OZL module measures 4.38 x 1.5 x 11.81 inches.
Features
1. High-precision analog output control
Core output characteristics of the 1771-OZL module:
- 16-bit high-resolution output (±0.05% FSR accuracy)
- Support 4-20mA/0-10V configurable output mode
- Fully isolated design between channels (anti-interference ability up to 1500Vrms)
Typical applications: precision process control (such as chemical reactors, constant pressure water supply systems)
2. Intelligent calibration and diagnostic functions
Intelligent maintenance features of this module:
- Automatic zero/full scale calibration (reduces manual debugging time)
- Real-time output current/voltage readback verification (ensures signal accuracy)
- Open circuit/short circuit alarm function (LED and software dual prompts)
- Typical applications: key instrument control (such as oil pipeline pressure regulation)
3. Industrial-grade reliability and compatibility
1771-OZL's durable design:
- -25℃~60℃ wide operating temperature range (adaptable to extreme environments)
- CE/UL/cUL certified (meets global safety standards)
- Plug and play, compatible with 1771 series backplanes
- Typical applications: harsh industrial scenarios such as metallurgy and energy
