FF-SRT Time Delay Module
FF-SR Series
FEATURES
• Complies with the Machinery Directive
98/37/EC, IEC 255, VDE 0435, and
UL 508
• Provides a delay after module is
de-energized
S
uitable for interfaces
up to
CATEGORY 1
per EN 954-1
• Output: one NC, one NO positive-guided
contacts
• Available with one or two time delay
circuits (channels)
• Available with fixed or selectable delay
up to 30 seconds
• LED status indication
• Mechanical life up to ten million
operations
• Electrical life up to 300,000 operations
• Switching current up to 8A
• Voltage drop protection
The FF-SRT Time Delay module provides a time delay before a safety interface is
opened safely.
If a two-channel version is used, the output contacts of the two time delay circuits
are connected in series. When the displayed time has elapsed, the safety contacts
within the module open safely, even if one of the other contacts is welded.
• 45 mm (1.77 in.) width
When power is applied to the module (A1/A2), the normally closed contact (15/16)
will open immediately and the normally open contact (27/28) will close.
APPLICATIONS
• Time delay required before
disconnection of safety interface circuit
After power is removed from the module (A1/A2), the normally closed contact (15/
16) will close and the normally open contact (27/28) will open after the fixed or set
time has elapsed.
For example, this module may be used with an emergency stop module. The emer-
gency stop module will immediately forward the emergency stop condition to the
machine control circuitry. The time delay module can be used to keep some non-
safety related machinery operating (door locked) for a short period of time to avoid
an unsafe condition or simplify the machine startup cycle.

Note 1: Total operations = Operations at power factor 1
multiplied by the limitation factor. If the power factor is 0.5
at 230 Vac, 2A (300,000 operations), the limitation factor is
0.70. 300,000 x 0.70 = 210,000 total operations.
Note 2: Install arc suppression device across load to avoid
module contact arcing and ensure specified relay life ex-

The example shows an emergency stop circuit with a motor using a speed driver. When an emergency stop condition occurs (e. g. the emergency
push-button is pressed), the speed driver is shut down immediately via the emergency stop module FF-SRS5935 and the dangerous movement of
the motor is stopped. When the delay time has elapsed, the power will be removed via the FF-SRT time delay module. External, positive guided
relays have to be monitored in the S33/S34 loop by its normally closed contacts.
