Logic Architecture and Hardwired Configuration

The DMA 111 uses hardwired logic instead of software programming. This module contains 16 equivalent logic gates for signal processing. You configure the logic function using jumpers on the PCB. The Schneider DMA 111 accepts eight 24 V DC input signals from sensors. It processes these signals through the selected logic configuration. Six relay outputs then switch loads based on the logic result.

Input Characteristics and Signal Conditioning

This Logistat module features eight digital input channels for field devices. Each input accepts 24 V DC signals from 19.2 to 30 V DC. The input current draws 7 milliamperes at nominal voltage. Input response time measures 10 milliseconds for reliable detection. The Schneider DMA 111 includes eight green LEDs for input status. Each LED lights up when its corresponding input receives a valid signal.

Output Configuration and Relay Specifications

The DMA 111 provides six relay output channels for load switching. Each relay offers a normally open single-pole single-throw (SPST) contact. Relays switch up to 2 amperes at 250 V AC or 30 V DC. Output response time measures 15 milliseconds from logic change to contact closure. Six red LEDs show the status of each output relay. An internal suppression diode protects against inductive load kickback.

Logic Functions and Jumper Configuration

You select the logic function for each output using jumper positions. Available functions include AND, OR, NOT, NAND, NOR, and XOR. The Schneider DMA 111 allows combination of multiple inputs per output. Jumpers also select between normally open and normally closed input logic. A configuration chart on the module housing guides jumper placement. No software or programming device is necessary for setup.

Physical Dimensions and Installation Guidelines

The Schneider DMA 111 weighs 0.300 kilograms for secure DIN rail mounting. Its height measures 100mm, width 50mm, and depth 120mm. Install this Logistat module on standard 35 mm DIN rails. The module consumes 2 watts from the 24 V DC power supply. It operates reliably from 0°C to +55°C ambient temperature. Use external fuses for output circuit protection.

Energy Storage and Passive Operation

The DMA 111 stores no electrical energy internally. It contains zero batteries or capacitors of any kind. Hence, this Logistat module requires no periodic maintenance whatsoever. You will never replace batteries or perform discharge procedures. The Schneider DMA 111 draws power only for input sensing and relay coils. Its hardwired design contains no software to crash or corrupt.
