Many technicians connect 110V AC to the "r6" power terminals. The manual states: "Power supply terminals are for DC ONLY. AC will destroy the unit instantly."
Typically features 6 Relay Outputs and 10 Digital Inputs (standard for R6 series hardware).
If the M91-T4-R6-ZK1 is the first or last device on the physical network bus, enable the internal 120-ohm termination resistor by setting the onboard DIP switch marked "TERM" to the ON position. 4. Programming and Configuration
Typical power requirements (12V to 24V DC). M91-t4-r6-zk1 Manual
A: Yes. The manual details how to configure the built-in PID function blocks (Auto-tune mode on initial startup for heating/cooling).
The M91 features a built-in serial port that can be configured via internal jumpers.
Maintain at least 50mm (2 inches) of free space around all sides of the unit to ensure adequate convective cooling. 3. Hardware Installation and Wiring Many technicians connect 110V AC to the "r6" power terminals
To configure the communication port, you will need to open the controller's casing. Before proceeding, . Touch a grounded object to discharge any electrostatic charge before handling the controller. Locate the four slots on the sides of the controller and carefully open the casing. Inside, you will find the jumper settings shown in the manual. Adjust these jumpers to select RS232 or RS485 mode. You can also set the RS485 termination by adjusting specific jumpers. After making changes, gently replace the PCB board, ensuring all pins fit correctly.
Press the bottom front of the module firmly toward the rail until the spring-loaded clip clicks securely into position.
"Do not observe the internal gears while the R6-node is in a state of flux, as the human optic nerve cannot resolve non-linear geometry." The Maintenance If the M91-T4-R6-ZK1 is the first or last

Each of the six relays (R1 through R6) is a Form C (SPDT) contact. The manual shows that NO (Normally Open) and NC (Normally Closed) terminals are clearly marked. For inductive loads (motors, solenoids), the manual mandates external flyback diodes.
Allow at least 10mm of space between the controller’s top/bottom edges and any enclosure walls.
