Unitronics M91-T4-R6-ZK1 is a specialized version of the M91 series micro-PLC (Programmable Logic Controller), often utilized as a proprietary controller for specific industrial equipment such as ZEKS air dryers. As an "All-in-One" OPLC (Operator Panel + PLC), it combines a programmable controller with a built-in textual HMI (Human-Machine Interface), featuring a 2-line by 16-character LCD and a 16-button keypad. Core Technical Specifications

According to documentation from Unitronics and industrial suppliers like Radwell International, the model typically includes:

Onboard I/O: Features 6 digital inputs (DC 24V) and 6 relay outputs (rated up to 5A).

Expansion Capabilities: It includes an I/O expansion port that allows for adding up to 96 additional I/Os through external modules.

Communication: Equipped with an RJ-11 port that supports RS232 or RS485 communication, enabling MODBUS connectivity and PC programming via U90 Ladder software.

Environmental Rating: The "T4" designation indicates suitability for mounting on the flat surface of Type 4X enclosures. Operational Features

The manual for this series highlights its design for small-to-medium automation tasks such as water treatment, oven control, and automated production. A key distinction for the ZK1 variant is its proprietary nature; it is often pre-programmed with password-protected OEM code for specific machinery, which may limit general-purpose reprogramming without authorized software or access. Unlike modern PLCs using IEC 61131-3, the M91

💡 Key Takeaway: The M91-T4-R6-ZK1 serves as a compact, rugged control solution that eliminates the need for a separate PLC and HMI, though users should note that the "ZK1" suffix often indicates custom OEM firmware for specific industrial dryers or compressors.
