Specialty Relays 

## **VTM1 Series, On-Delay, Timing Module** 

## **Timing Specifications** 

## **Output Switch Data** 

**Timing Mode** — On-Delay **Timing Ranges** — 0.5 to 10 / 3 to 60 sec.; 0.5 to 10 / 3 to 60 min. **Timing Range Selection** — Screwdriver select via recessed 8-position selector dial. 

**Arrangement** — Solid state 1 Form A (SPST-NO) **Rating** — 1A, inductive, at nominal operating voltage. **Expected Electrical Life** — 10,000,000 operations at rated load. **Initial Dielectric Strength** — Between Terminals and Mounting — 3,000VAC rms. Between Input and Output — 1,500VAC rms. 

**Timing Adjustment** — External resistor or potentiometer. An external resistance of 1 megohm is required to obtain the maximum time for all ranges. To determine the actual resistance needed to obtain the required time delay, use the following formula: 

> [- T][MIN][)] RT =[(][T][RE][Q] x 1,000,000 ohms TMAX - TMIN 

## **Product Facts** 

**Accuracy** — Repeat Accuracy — ±1% Overall Accuracy — ±2% at R = 1 megohm **Reset Time** — 100 ms, max., before time-out; 10 ms, max., after time-out.
