Technical Specifications / Parameters Parameter Specification Manufacturer Order Code 1SVR430740R9000 Catalogue Type CM-TCS.26 Brand / Series ABB CM-TCS Series (Digital Timer Relays) Device Type Digital Timer Relay (Time Delay Relay) Operating Modes Multiple modes, typically including: • On-Delay (Delay on Make) • Off-Delay (Delay on Break) • Interval / One-Shot • Flicker (Flashing) • Symmetrical / Asymmetrical Pulse Output Time Delay Range Wide range, adjustable via front DIP switches or rotary dials. Typically from 0.1 seconds up to 100 hours (selectable ranges). Setting Accuracy High accuracy (typically ±0.5% of set value or better). Supply Voltage (Us) Wide-range 24...240V AC/DC (auto-sensing). Input Signal The supply voltage also serves as the control signal. Timer starts upon application (for on-delay) or removal (for off-delay) of supply voltage. Output Relay 1 Changeover (CO) Contact (SPDT - 1 NO + 1 NC) • Contact Rating: Typically 8A / 250V AC (resistive load). Reset Function Instantaneous reset upon power interruption (for on-delay). For off-delay, behavior depends on the specific mode. Status Indication LEDs for Power (Supply) and Output Status (shows when the output relay is energized). Time Setting Method Via rotary DIP switches or thumbwheel switches on the front for selecting the time multiplier (e.g., x0.1s, x1s, x1min) and digit dials for setting the precise value. Mounting DIN Rail Mounting (35mm). Module Width 22.5mm (1 module width). Operating Temperature -20°C to +60°C. Front Protection Degree IP40. Standards & Approvals IEC/EN 60255, UL 508, CSA C22.2 No. 14, CE, cULus. Typical Applications • Motor Star-Delta starting sequence control. • Conveyor belt sequencing and interlocking. • Pump duty cycling (alternating pumps). • Lighting control (stairwell lighting, signage). • Machine tool control cycles (dwell times, cool-down periods). • Ventilation system control (delayed shut-off).
