GENERAL NOTES
1. Relay contacts will exhibit no chatter in excess of 10 μsec or transfer in excess
of 1 μsec.
TYPICAL LOGIC INTERFACE
(See Note 8)
2. “Typical” characteristics are based on available data and are best estimates. No
on-going verification tests are performed.

3. Unless otherwise specified, parameters are initial values.
4. For reference only. Coil resistance not directly measurable at relay terminals due
to internal series semiconductor. 431DD and 431T only.
5. Unless otherwise specified, relays will be supplied with either gold-plated or
solder-coated leads.
6. The slash and characters appearing after the slash are not marked on the relay.
7. Limit Base Emitter current to 15 mAdc.
8. Applicable to all coil voltages. See Base current to turn on.
9. Screened HI-REL versions available. Contact factory.

Notes:
Logic 1 activates the relay.
Logic 0 de-activates the relay.
Vcc = logic bias power.
Vr = coil energization voltage.
