Section 1
General Description
The TDM is a multipurpose timing module that can be
used for a variety of applications. Its unique design and
open architecture allows the TDM to be used in any
application that requires timing control of up to two
outputs with up to four inputs. Common applications
include: simple time delay, vestibule door sequencing
(only one device required) and electric lock/automatic
door operator sequencing.
The four inputs on the TDM allow sequencing or
independent operation of the two outputs. Input 1 will
sequence Outputs 1 then 2. Input 2 will sequence
Outputs 2 then 1. Input 3 will operate Output 1
independently. Input 4 will operate Output 2
independently.
Both outputs on the TDM are fully programmable for "on
time" duration as well as the delay time between the two
outputs from 0 to 99 seconds.
CAUTION:
Devices to be controlled by the TDM
must be low voltage (12-24V) but can be
inductive loads. Surge suppressors are standard
on the TDM.
WET/DRY CONTACT OPTION:
The TDM has the option to supply power to Relay Output
1 contacts. This is known as having a "Wet" contact
instead of the conventional "Dry" contact closure. To use
output 1 as a "Wet" contact, change the jumper setting
(see Figure 1). The voltage supplied to Output 1 will be
the same as the voltage supplied to the input power wires
of the TDM.
WARNING:
Changing jumper settings to enable
the “Wet” Contact option will apply a voltage to
the Output 1 relay contact. Please ensure that
any device connected to this output is capable of
accepting voltage. Failure to do so may result in
damage to the device.
Section 2
Basic Installation
The physical placement of the TDM is typically in the door
operator housing area since the power supply and
operator control are already in this location. The TDM
layout and wiring connections are shown in Figure 1.
Included on the following pages are detailed wiring and
programming instructions for three common applications.

After successfully wiring the TDM for your application,
refer to Figure 5 for the operating display explanations
and additional programming options. For additional
technical assistance, please contact us toll-free at 1-800-

NOTICE:
These instructions are provided for your
convenience. Please verify your installation is in
compliance with all local electrical codes.
