VTM2ADD

Specialty Relays 

## **VTM2 Series, Off-Delay, Timing Module** 

## **Timing Specifications** 

## **Output Switch Data** 

**Timing Mode** — Off-Delay **Timing Ranges** — 0.5 to 10 / 3 to 60 sec.; 3 to 60 min. 

**Arrangement** — Solid state 1 Form A (SPST-NO) 

**Rating** — 1A, inductive, at nominal operating voltage. 

**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: 

**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. 

> [- T][MIN][)] RT =[(][T][RE][Q] x 1,000,000 ohms TMAX - TMIN **Accuracy** — Repeat Accuracy — ±1% Overall Accuracy — ±2% at R = 1 megohm
