Category Specification
Supply Protection Cir-
cuitry Protected against transient voltages and reverse polarity
Overvoltage Category Output relay contact voltage of 1V to 150V ac/dc: category III
Output relay contact voltage of 151V to 250V ac/dc: category III, if appropriate overvoltage reduction is provi-
ded, as described earlier.
Pollution Degree 2
Relay Outputs 4 normally open (N.O.) output channels and 1 normally closed (N.C.) output
Each normally open output channel is a series connection of contacts from two forced-guided (mechanically
linked) relays, K1-K2. The normally closed Aux. output channel is a parallel connection of contacts from two
forced-guided relays, K1-K2.
Contacts: AgNi, 5 μm gold-plated
Low Current Rating: The 5 μm gold-plated contacts allow the switching of low current/low voltage. In these
low-power applications, multiple contacts can also be switched in series (e.g., “dry switching”). To preserve
the gold plating on the contacts, do not exceed the following max. values at any time:
Min. voltage: 1V ac/dc
Min. current: 5 mA ac/dc
Min. power: 5 mW (5 mVA) Max. voltage: 60V
Max. current: 300 mA
Max. power: 7 W (7 VA)
High Current Rating: If higher loads must be switched through one or more of the contacts, the minimum and
maximum values of the contact(s) changes to:
Minimum Maximum
Voltage: 15V ac/dc N.O. Safety Contacts (13-14, 23-24, 33-34,
43-44): 250V ac / 24V dc, 6A resistive
B300, Q300 (UL508)
Current: 250 mA ac/dc N.C. Auxiliary Contact (51-52): 250V ac / 24V
dc, 5A resistive
B300, Q300 (UL508)
Power: 5 W (5 VA)
Minimum Maximum — IEC60947-5-1
Voltage: 15V ac/dc N.O. Safety Contacts:
AC-1: 250V ac, 6A; DC-1: 24V dc, 6A
AC-15: 230V ac, 3A; DC-13: 24V dc, 4A
Current: 250 mA ac/dc N.C. Auxiliary Contact:
AC-1: 250V ac, 5A; DC-1: 24V dc, 5A
AC-15: 230V ac, 2A; DC-13: 24V dc, 4A
Power: 5 W (5 VA)
Mechanical life: > 50,000,000 operations
Electrical life: 150,000 cycles @ 1500 VA; 1,000,000 cycles @ 450 VA; 2,000,000 cycles @ 250 VA;
5,000,000 cycles @ 125 VA
NOTE: Transient suppression is recommended when switching inductive loads. Install suppressors across
load. Never install suppressors across output contacts (see Warning, Wiring of Arc Suppressors).
Solid-State Outputs Two non-safety solid-state dc outputs
Output circuits require application of +12-24V dc ± 15% at terminal Y31; dc common at Y30.
