Specifications

Supply Voltage and Current

A1-A2: 115V ac (AT-GM-11KM) or 230V ac (AT-
HM-11KM), +/- 15%; 50/60Hz
B1-B2: 24V dc, +/- 15%, 10% max. ripple

Supply Protection Circuitry

Protected against transient voltages and reverse polari-
ty

Power Consumption

Approx. 4 W/7 VA

Output Configuration

Outputs (K1 and K2): two redundant (total of four)
safety relay (forced-guided) contacts
Contact ratings:
Maximum voltage: 250V ac or 250V dc
Maximum current:

N.O. Safety Output: 6A ac or dc (resistive load)
N.C. Auxiliary Output (51/52): 5A ac or dc (resis-
tive load)

Maximum power:

N.O. Safety Output: 1500 VA, 200 watts
N.C. Auxiliary Output (51/52): 1250 VA, 200 watts

Mechanical life: 50,000,000 operations
Electrical life: 150,000 cycles (typically @ 1.5 kVA
switching power)
NOTE: Transient suppression is recommended when
switching inductive loads. Install suppressors across
load. Never install suppressors across output contacts
(see Warning in

Electrical Installation

on page 10).

Auxiliary Supply Voltage (for solid-state outputs)

24V dc @ 1A (applied between Y30 and Y31)

Auxiliary Solid-State Output Current

500 mA max., short circuit protected, Y32 is a PNP out-
put, Y33 is an NPN output

Output Response Time

35 milliseconds maximum ON to OFF

Input Requirements

Outputs from actuating devices must each be capable
of switching up to 20 mA @ 12V dc

Simultaneity Monitoring Period

≤ 500 milliseconds

Z1/Z2 Courtesy Voltage

24V dc @ 150 mA (for STB button power, separate
from Auxiliary output, unregulated)

External Device Monitoring (EDM)

One pair of terminals (Y1 and Y2) are provided to mon-
itor the state of external devices controlled by the safe-
ty outputs. Each device must be capable of switching
15 to 30V dc at 10-50 mA.

Muting Device Inputs (M1, M2)

The muting devices work as a pair (M1 and M2). The
simultaneity requirement is that they be “closed” within
3 seconds of each other to initiate a mute condition or
allow a mute cycle, assuming all other conditions are
met. Each muting device must be capable of switching
15 to 30V dc at 10-50 mA.

Mute Enable Input (ME)

Mute Enable input must be closed in order to start a
mute cycle. Opening this input after a mute cycle has
begun has no effect. The switching device must be ca-
pable of switching 15 to 30V dc at 10-50 mA.

Safety Stop Interface (SSI)

This input consists of two concurrent channels (SSI-A
and SSI-B) and is always active. Any time either or
both channels open, the Safety Outputs will go OFF.
When using the SSI, the external device must be capa-
ble of switching 15 to 30V dc at 10-50 mA.

Status Indicators

6 green LED indicators and 1 red LED indicator (see

Figure 1. AT-xM-11KM Status Indicators

on page 3 and

LED Indicators

on page 16)

Housing

Polycarbonate. Rated NEMA 1 (IEC IP20)

Mounting

Mounts to standard 35 mm DIN rail track. Safety Mod-
ule 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
