| Datasheet | Download Datasheet |
The TimeMark TMC430 is a digital pump controller for a 24V DC supply. It runs up to 3 pumps on a 4-20 mA transducer, or 2 pumps with float back-up or on floats only.
Sensing: 4-20 mA transducer and / or float switches. Pumps: up to 3, alternating or fixed lead. Input: 1 x 4-20 mA; 12 digital inputs (pump alarms: seal fail, over-temperature, contact failure). Controls: hand-off-auto per pump from the menu or USB; 24 V DC supply not included (TimeMark 97080701 optional). Display: 128 x 64 graphic LCD; event log with real-time clock. Communication: RS-485 Modbus; USB (Windows software).
Output: 4 x SPDT (control / alarm), 10 A at 240 V AC resistive. Signal output: 4-20 mA retransmission. Alarms: level alarm relay (high or low per mode). Mounting: flush or surface mount (DIN rail kit 81008601 optional). It operates from -20 to +70 °C.
