Power
24V dc, ± 20%
Model SC22-3: 0.4 A (Controller only), 5.9 A (all outputs ON @ full rated load)
Model SC22-3E: 0.4 A (Controller only), 4.9 A (all outputs ON @ full rated load)
The Controller should be connected only to a SELV (safety extra-low voltage, for circuits without earth ground) or a
PELV (protected extra-low voltage, for circuits with earth ground) power supply.
Safety and Non-Safety Inputs (22 terminals)
Input ON threshold: > 15V dc (guaranteed on), 30V dc max.
Input OFF threshold: < 5V dc (guaranteed off with any 1 fault), –3V dc min.
Input ON current: 8 mA typical @ 24Vdc, > 2 mA (guaranteed with 1 fault)
50 mA peak contact cleaning current @ 24V dc
Sourcing current: 30 mA minimum continuous (3V dc max. drop)
Input lead resistance: 300 Ω max. (150 Ω per lead)
Input requirements for a 4-wire safety mat:
• Max. capacity between plates: 0.5 µF
• Max. capacity between bottom plate and ground: 0.5 µF
• Max. resistance between the 2 input terminals of one plate: 20 Ω
Safety Outputs (6 terminals, 3 redundant outputs)
Rated output current:
Model SC22-3: 0.75 A max. @ 24V dc (1.0V dc max. drop)
Model SC22-3E: 0.5 A max. @ 24V dc (1.0V dc max. drop)
Output OFF threshold: 0.6V dc typical (1.2V dc max. guaranteed with 1 fault)
Output leakage current: 50 µA max. with open 0V
Load: 0.1 µF max., 1 H max., 10 Ω max. per lead
Status Outputs (10 terminals)
Rated output current: 0.5A @ 24V dc (individual), 1.0 A @ 24V dc (total of all outputs)
O1 to O8 (General Purpose)—Output OFF voltage: < 0.5V dc (no load), 22 KΩ pull down to 0V
O9 and O10 (General Purpose or Monitored Mute Lamp)—
Output OFF voltage: Internal 94 KΩ pull up to 24V dc supply
Output ON/OFF threshold: 15V dc +/−4V dc @ 24V dc supply
NOTE: For O9 and O10 (when configured as a monitored mute lamp output), if a short circuit or other fault condi-
tion causes the output to drop below this threshold while the output is ON, a lockout will occur. If an open circuit or
other fault condition causes the output to rise above this threshold while the output is OFF, a lockout will occur.
Response and Recovery Times
Response Time (ON to OFF): 10 ms max. (with standard 6 ms debounce; this can increase if debounce time increases.
Refer to the configuration summary for actual response time.)
