Key Specifications Summary
Category Specification
Product Type Programmable Logic & Arithmetic Unit (Software-configurable)
Series/Type Yokogawa UTAdvanced Programmable Controller (UM1L)
Input Signal 1 channel, 4 to 20 mA DC (Can be used as a variable in logic)
Output 1 1 channel, 0 to 20 mA DC (Programmable analog output)
Output 2 1 channel, SPDT (Form C) Relay Contact (Programmable digital output)
Core Function User-Programmable. Can execute logic (AND, OR, NOT, timers, counters), arithmetic functions (+, -, *, /, square root), and comparisons based on input values and internal logic.
Power Supply The housing unit requires an external 24 VDC power supply.
Isolation Input, Analog Output, Relay Output, and Power are galvanically isolated.
Configuration Requires dedicated software (e.g., Yokogawa's dedicated configurator) to create and download the logic program.
Installation DIN-rail mount. Must be installed in a UTAdvanced housing unit.
Typical Application Complex interlock control: E.g., Start a pump (using the relay) only if the tank level (4-20mA input) is above 50% AND a remote start permission is given (via another module's logic). The analog output could be used to send a calculated value to a display.
