The Honeywell TC-POB041 offers four digital output channels. All channels share a single supply reference. This module meets CENELEC II (1) 2G EEx ia/ib IIB/IIC T4 standards. Therefore, you can use it safely in explosive gas environments.
Output voltage reaches 11V at 45mA current. The de-energized state is the default failure condition. Response time is fast at just 1ms for all channels. Additionally, switching frequency goes up to 10kHz. These features make the TC-POB041 ideal for high-speed digital control tasks.
Output Capacity: Four channels, single supply reference.
Output Voltage: 11V at 45mA.
Failure State: De-energized.
Response Time: 1ms module input/output delay for all channels.
Switching Frequency: 10kHz maximum.
For field circuit values, the TC-POB041 permits Uo = 27.4V and Io = 110mA. Inductance limits are 8mH for IIB and 2mH for IIC. Capacitance limits are 677nF for IIB and 87nF for IIC. These values keep the output intrinsically safe per CENELEC requirements.
Power comes through the terminal base. Consumption is one power supply unit load. Power dissipation is 5W. Fault detection delay time is configurable for the entire module. This setting applies to all channels simultaneously.
The Honeywell TC-POB041 detects both lead breakage and short circuits. When a fault occurs, the module sends an alarm signal through the backplane bus. Additionally, the channel LED flashes red to indicate the problem.
Latch mode is configurable for the whole module. This means the setting applies to all four channels together. You cannot configure latch mode per channel individually. Fault detection delay time also applies globally to all channels.
Galvanic isolation exists between output and backplane bus. Isolation also separates output from power supply per DIN EN 50020. However, there is no isolation between outputs relative to each other. Plan your wiring accordingly.
To achieve EMC protection class, you must use shielded multicore cable. The TC-POB041 complies with DIN EN 50081-2 and DIN EN 50082-2 standards. It also follows NAMUR NE 21 recommendations.
Terminal assignments follow standard Honeywell Series 8 pinouts. Consult the installation guide for exact positions. Keyswitch position for this module is 7.
Ambient Temperature: –20°C to 70°C.
Storage Temperature: –20°C to 100°C.
Humidity: 95% non-condensing.
Pollution Gas Test: Level G3 per ISA-S71.04-1985.
Shock: 15g peak for 11ms duration.
Vibration: 2g from 10Hz to 500Hz per IEC 68-2-6.
Protection Class: IP20. For field installation, use a separate housing with IP54 or better.
Furthermore, the TC-POB041 weighs 0.282 kg. Dimensions are 76 x 94 x 46 mm (3.0 x 3.7 x 1.8 inches). These compact dimensions fit standard DIN rail mounting systems.
First, mount the module on a compatible Honeywell Series 8 terminal base. The base supplies intrinsically safe power. Next, set the keyswitch to position 7. Then connect field wiring using shielded multicore cable.
Configure fault detection delay time through the system software. Remember this setting applies to all four channels together. Latch mode is also configurable at module level. Finally, verify field circuit values do not exceed Uo = 27.4V or Io = 110mA.
For safe area installations, no additional housing is needed. For field installations, always use an IP54 enclosure or better. Follow DIN EN 50014 and DIN EN 50020 standards during all installation steps.

1. What is the switching frequency of the TC-POB041?
The Honeywell TC-POB041 supports up to 10kHz switching frequency. Response time is 1ms for all channels.
2. Can I configure fault detection per channel on this module?
No. Fault detection delay time applies to the whole TC-POB041 module. The setting affects all four channels simultaneously.
3. Is the TC-POB041 intrinsically safe for gas zones?
Yes. It carries CENELEC II (1) 2G EEx ia/ib IIB/IIC T4 certification. Use it in hazardous locations safely.
4. What is the failure state of this digital output module?
The failure state is de-energized. Outputs go to off condition when a fault or power loss occurs.
5. Does the TC-POB041 provide isolation between output channels?
No. There is no galvanic isolation between outputs. Isolation exists only between output and backplane bus, and output and power supply.
