IDENTIFYING THE SOLID STATE RELAYS
Thyristor firing
Firing mode Logic ON/OFF
Switching Firing starts and ends at zero voltage
Indication Thyristor firing is signalled by a green LED
Control
Signal type DC Logic or AC Logic
The signal type (DC or AC) is configured at the factory
according to the order code; it cannot be re-configured by
the user
DC signal Universal input: voltage or current.
Polarity insensitive: ‘+’ and ‘-’ can be crossed
‘On’ state Guaranteed conditions for firing:
voltage greater than 5Vdc or
current greater than 5mA
Maximum voltage: 32Vdc.
Maximum current (self-limited) 10mA at 32Vdc
‘Off’ state Voltage less than 2Vdc or current less than 0.5mA
AC signal 24 to 48 Vac Typical input impedance 2.2k
Ω
(50Hz & 60Hz)
‘On’ state Guaranteed conditions for firing:

Ω
(60Hz)
‘On’ state Guaranteed conditions for firing:
voltage from 85Vac to 253Vac
‘Off’ state Voltage less than 10Vac
