Product catalog summary
Installation and Setting:
Before installation, ensure the power supply is isolated. Connect the unit as required. Set the 'Range' to the desired position for seconds, minutes, or hours. Adjust the 'Set %' to the required percentage of the selected range. Apply power across terminals A1 and A2; the green LED will flash, indicating timing in progress. The relay will energize, and the red LED will illuminate. After the delay period, the relay will de-energize, and the red LED will extinguish, while the green LED remains lit. The process repeats by removing and reapplying power.
Technical Specification:
Supply voltage ranges from 12 to 230V AC/DC with a frequency range of 48-63Hz. The unit supports a supply variation of +/- 15% and is categorized under Overvoltage Category III. It has a rated impulse withstand voltage of 4kV. Power consumption varies with voltage, with maximum values of 3.4VA for AC and 0.95W for DC. The timing function is interval-based with seven selectable ranges from 0.1 seconds to 100 hours. The reset time is 100ms, with an accuracy of ±1% of the full scale. The unit operates within an ambient temperature range of -20 to +60°C and supports a relative humidity of up to 95%.
Output and Housing:
The unit features an SPDT relay output with ratings of 250V 8A for AC1 and 25V 8A for DC1. It has an electrical life of over 150,000 operations at rated load. The housing is made of orange flame-retardant material and weighs approximately 60g. It can be mounted on a 35mm DIN rail or directly on a surface using provided clips. Terminal conductor size is up to 2 x 2.5mm².
Approvals and Compliance:
The unit conforms to IEC 61812 and is CE, C-tick, and RoHS compliant. It meets EMC standards for immunity and emissions as per EN 61000-6-2 and EN 61000-6-4.
Function and Connection Diagrams:
The function diagram illustrates the operation of the output and supply terminals, while the connection diagram provides guidance on wiring the supply and relay outputs. The unit includes LED indicators for power supply status and relay output status.

Connect the unit as required. Installation work must be carried out by qualified personnel. Electrical life: Dielectric voltage: Rated impulse withstand voltage: Setting the unit. • Set the “Range” to the required position (depending on whether seconds, minutes or hours are required). • Set the “Set %” adjustment as required. The “Set %” is a % of the selected range; so for example, a 30% setting on the 1 – 10 hour range will give 3 hours. Housing: Weight: Mounting option: Terminal conductor size Orange flame retardant UL94 ≈ 60g On to 35mm symmetric DIN rail to BS EN 60715 or direct surface mounting via 2 x M3.5 or 4BA screws using the black clips provided on the rear of the unit. ≤ 2 x 2.5mm2 solid or stranded Applying power. • Apply power across terminals A1 and A2 and the green LED will start flashing indicating timing in progress. • The relay will energise (contacts 15 / 16 open and 15 / 18 closed) and red LED illuminate. • After the delay period “t” has elapsed, the relay will de-energise (contacts 15 / 16 and 15 / 18 open) and the red LED will extinguish. • The green LED will now remain permanently lit. • The whole timing process is repeated by removing and re-applying power. Conforms to IEC 61812. CE, C-tick and RoHS Compliant. EMC: Immunity: EN 61000-6-2 (EN 61000-4-3 10V/m 80MHz - 2.7GHz) Emissions: EN 61000-6-4 In accordance with IEC 61812, the green LED is permitted to extinguish during a voltage dip or momentary interruption of the power supply providing the state of the output relay does not change. The dip / interruption duration and levels are defined in the product standard. SETTING DETAILS 1. Power supply status / Timing (Green) LED 2. Relay output status (Red) LED 3. “Set %” adjustment 4.
