## **SCB/SCC Series, Specification Grade Discrete Plug-in, Time Delay Relay** 

## **Timing Specifications** 

## **Contact Data @ 25°C** 

## **Environmental Data** 

**Arrangements** — 2 Form C (DPDT) **Rating** — 10A @ 28VDC or 120VAC, resistive; 1/3 HP @ 120/240VAC; 345VA. Same polarity. 

**Timing Modes** — On-Delay, Off-Delay and Interval **Timing Ranges** — 6 to 180 cycles; 0.1 to 3 / 0.1 to 10 / 0.33 to 10 / 1 to 30 / 4 to 120 sec.; 0.33 to 10 / 1 to 30 / 2 to 60 min.; 0.33 to 10 hr. (All are +5%, – 0% of maximum values). 

**Temperature Range** — Storage — SCB and SCC — -40°C to +85°C Operating — SCB: -30°C to +65°C; SCC: -30°C to +50°C 

**Expected Mechanical Life** — 10 million operations **Expected Electrical Life** — 500,000 operations, min., at rated resistive load 

## **Mechanical Data** 

**Timing Adjustment** — Knob or fixed time (internal fixed resistor) — all models; customer supplied external potentiometer or resistor — On-Delay and Interval models only. 

**Mounting/Termination** — SCB — UL recognized. Optional 8- or 11-pin octal-type sockets may be ordered separately. SCC — 8- or 11-pin octal type sockets supplied with timer. (Must be used to qualify as "UL Listed" device.) **Weight** — SCB: 5.3 oz. (149g) approx.; SCC: 7.5 oz. (210g) approx. 

**Initial Dielectric Strength** — Between Terminals and Case — 1,000VAC plus twice the nominal voltage for one minute. 

**Accuracy** — Repeat Accuracy — ±0.5% ±0.004 sec. Overall Accuracy — ±2% max. 

## **Input Data @ 25°C** 

**Voltage** — See Ordering Information section for details. 

## **Product Facts** 

**Reset Time** — 25 ms. 

- n **On-Delay, Off-Delay and Interval timing modes** 

**Power Requirement** — 3W, max. 

**Relay Operate Time** — Off-Delay mode — 30 ms; Interval mode — 20 ms.. 

Transient Protection: Non-repetitive transients of the following magnitudes will not cause spurious operation of affect function and accuracy.
