See Figure 5.
Protected against transient voltages and reverse polarity
Output Configuration
Outputs (K1 & K2): four redundant (i.e. total of eight) safety relay (forced-guided) contacts – AgNi, gold flashed
Contact ratings:
Maximum voltage:
250V ac or 250V dc
Maximum current:
5 A ac or dc (resistive of load)
Minimum current:
30 mA @ 24V dc
Maximum power:
1250VA, 200W
Mechanical life:
50,000,000 operations
Electrical life:
100,000 at full resistive load
NOTE: Transient suppression is recommended when switching inductive loads. Install suppressors
across load. Never install suppressors across output contacts (see Warning, page 6).
Auxiliary Monitor Output (K3):
One non-safety relay contact monitors state of outputs - open when both K1 and K2 are energized;
closed when either K1 or K2 are deenergized
Maximum switching voltage:
125V ac or V dc
Maximum switching current:
500 mA (resistive load)
Solid-state Monitor Outputs:
Two non-safety solid-state dc relays -
Output at Y32 monitors state of outputs - contacts (output high) when both K1 and K2 are energized
Output at Y35 conducts (output high) when internal power supply is ok
Output circuits require application of +24V dc +/-15% at terminal Y31; dc common at Y30
Maximum switching current:
20 mA at 24V dc
Both outputs are protected against short circuits
Output Response Time
2-Channel applications:
30 milliseconds maximum
1-Channel applications:
70 milliseconds maximum
Status Indicators
3 green LED indicators:
Power ON
K1 energized
K2 energized
1 red LED indicator responds to fault of internal power supply, ground fault, or cross-short of input channels
Input Requirements
Emergency stop switch must have two normally closed contacts each capable of switching
30 to 100 mA @ 12 to 18V dc (in 2-channel operation).
Reset switch must have one normally open contact capable of switching 40 to 100 mA @ 12 to 18V dc.
Housing
Polycarbonate. Rated NEMA 1; IEC IP20
Mounting
Mounts to standard 35 mm DIN rail track. Safety Module must be installed inside an enclosure rated NEMA 3
(IEC IP54), or better.
Vibration Resistance
10 to 55Hz @ 0.35 mm displacement per IEC 68-2-6
Operating Conditions
Temperature:
0° to +50°C (+32° to 122°F)
Maximum Relative Humidity:
90% @ +50°C (non-condensing)
Supply Voltage and Current
A1-A2: 115 ac (model ES-GA-5A) or 230V ac (model ES-HA-5A), +/- 15%; 50/60 Hz
B1-B2: 24V dc, +/-, 10% max. ripple
Power consuption: approx. 4W/7 VA
Minimum OFF-State
Recovery Time
500 ms
