5.3 Adding Electronic Options
to Your Accutronix MX Actuator
Listed below are the options available for the Accutronix MX.
1. Modutronic option; does not require any hardware, however, a “keycode” from the factory is required.
2. Two-speed timer; does not require any hardware, however a “keycode” from the factory is required.
3. APT option; Analog Position Transmitter, non-contracting 4-20 mA position transmitter requiring the addition of the
I/O (input/output) option board.
4. ATT option; Analog Torque Transmitter, non-contacting 4-20 mA torque transmitter requiring the addition of the I/O
(input/output) option board.
5. AR option; Alarm Relays, three non-latching relays requiring the addition of the I/O (input/output) board. Non-
latching relays change state when power is removed from the actuator, e.g. if the relay is CLOSED and power is
removed, the relay will OPEN.
6. DDC option; network communication field board that is required for two-wire twisted pair, MODBUS communication.
7. FF option; network communications board required for Foundation Fieldbus communication.
The procedure for adding electronic options to your MX actuator is as follows:
• For adding the Modutronic and two-speed timer options, the actuator QA Stamp ID must be supplied in order to
acquire the necessary keycode.
• Each MX actuator is supplied a unique “QA Stamp ID.” This number is assigned during the end-of-line test sequence
for each unit.
