Smart 200 Standard Expansion Modules
Expand Smart 200 Standard PLC with Digital I/O, Analog I/O, and Temperature modules (PT100 / Thermocouple / NTC), including mixed high-density modules for advanced projects.
- Need more sensors/actuators → Digital I/O
- Need transmitters & control signals → Analog I/O
- Need temperature control → PT100 / TC / NTC
- Need large channel count → look for DP in Order Number

What does “DP” mean in the Order Number?
For some high-density expansion modules (e.g., 32DI / 32DQ / 16AI / 8AQ / multi-signal types), the PLC configuration may require selecting EM DP01 during system configuration. This ensures correct module identification and parameter setup.
Digital I/O Expansion Modules
Discrete input/output expansion for sensors, push buttons, relays, contactors, solenoids and general loads. Choose relay outputs for universal switching, or transistor outputs for high-speed switching.
| Resource | Configuration Selection | Order Number |
|---|---|---|
| EM DE08 | 8 Inputs | EM DE08 (8DI) |
| EM DE16 | 16 Inputs | EM DE16 (16DI) |
| EM DE32 | 32 Inputs | EM DP01 (DP) |
| EM DR08 | 8 Relay Outputs | EM DR08 (8DQ Relay) |
| EM QR16 | 16 Relay Outputs | EM QR16 (16DQ Relay) |
| EM QR32 | 32 Relay Outputs | EM DP01 (DP) |
| EM DT08 | 8 Transistor Outputs | EM DT08 (8DQ Transistor) |
| EM QT16 | 16 Transistor Outputs | EM QT16 (16DQ Transistor) |
| EM QT32 | 32 Transistor Outputs | EM DP01 (DP) |
| EM DR16 | 8 In/8 Relay Out | EM DR16 (8DI/8DQ Relay) |
| EM DR32 | 16 In/16 Relay Out | EM DR32 (16DI/16DQ Relay) |
| EM DT16 | 8 In/8 Transistor Out | EM DT16 (8DI/8DQ Transistor) |
| EM DT32 | 16 In/16 Transistor Out | EM DT32 (16DI/16DQ Transistor) |
- Relay outputs are ideal for universal switching (contactors, solenoids, lamps).
- Transistor outputs are recommended for high-speed pulse and frequent switching.
- High channel count models (32DI/32DQ) may require EM DP01 during configuration.
Analog I/O Expansion Modules
Analog input/output modules support voltage or current signals for industrial transmitters and control devices (e.g., pressure/flow/level sensors, PID outputs, VFD speed reference, valve positioning).
| Resource | Configuration Selection | Order Number |
|---|---|---|
| EM AE04 | 4 (Voltage or Current) Inputs | EM AE04 (4AI) |
| EM AE08 | 8 (Voltage or Current) Inputs | EM AE08 (8AI) |
| EM AE16 | 16 (Voltage or Current) Inputs | EM DP01 (DP) |
| EM AE32 | 32 (First 8 channels voltage/current, last 24 current) Inputs | EM DP01 (DP) |
| EM AQ02 | 2 (Voltage and Current) Outputs | EM AQ02 (2AQ) |
| EM AQ04 | 4 (Voltage and Current) Outputs | EM AQ04 (4AQ) |
| EM AQ08 | 8 (Voltage and Current) Outputs | EM DP01 (DP) |
| EM AM03 | 2 In/1 Out (Voltage and Current) | EM AM03 (2AI/1AQ) |
| EM AM06 | 4 In/2 Out (Voltage and Current) | EM AM06 (4AI/2AQ) |
| EM AM12 | 8 In/4 Out (Voltage and Current) | EM DP01 (DP) |
| EM AM16 | 8 In/8 Out (Voltage and Current) | EM DP01 (DP) |
- Choose AE for analog inputs, AQ for analog outputs, and AM for combined AI + AO.
- AE32: first 8 channels support voltage/current; last 24 channels are current-input type.
- High channel count modules may require EM DP01 during configuration.
Temperature & Mixed Signal Modules
Temperature acquisition for heaters, ovens, drying lines and multi-zone control. Choose PT100 (RTD) for accuracy and stability, Type K Thermocouple for wide temperature range, or NTC (10K, 3950) for cost-effective multi-point monitoring. Mixed modules combine temperature + analog inputs.
| Resource | Configuration Selection | Order Number |
|---|---|---|
| EM AR02 | 2-Channel PT100 Inputs | EM AR02 (2AI RTD) |
| EM AR04 | 4-Channel PT100 Inputs | EM AR04 (4AI RTD) |
| EM AR08 | 8-Channel PT100 Inputs | EM DP01 (DP) |
| EM AT04 | 4-Channel Type K Thermocouple | EM AT04 (4AI TC) |
| EM AT08 | 8-Channel Type K Thermocouple | EM DP01 (DP) |
| EM AN16 | 16-Channel NTC (10K, 3950) | EM DP01 (DP) |
| EM EN88-8AI8NTC | 8 NTC, 8 Analog Inputs | EM DP01 (DP) |
| EM EN4C-4AI12NTC | 12 NTC, 4 Analog Inputs | EM DP01 (DP) |
- PT100 (RTD) is recommended for higher accuracy and stable measurement.
- Type K Thermocouple is suitable for higher temperature ranges.
- NTC (10K, 3950) is cost-effective for multi-point temperature monitoring.
- Mixed models EN88 / EN4C combine NTC + analog inputs for dense signal acquisition.
FAQ
No. Only some high-density models show EM DP01 (DP) in the Order Number, which indicates DP selection during configuration.
AE = Analog Inputs, AQ = Analog Outputs, AM = Analog Inputs + Outputs in one module.
