TC-PIB161 Honeywell 16-Channel Digital Input Module

TC-PIB161 Honeywell Digital Input Module

• The Honeywell TC-PIB161 provides a quiescent voltage of approximately 8Vdc with a short-circuit current of 8mA. The switching point sits between 1.2mA and 2.1mA with a hysteresis of 0.2mA.
• Input pulse length and pulse pause both exceed 25 microseconds for reliable signal detection. The maximum switching frequency reaches 1kHz for high-speed digital applications.
• Response time measures 1ms for all channels. Backplane bus update ranges from 1ms to 64ms depending on your filter time configuration.
• The TC-PIB161 consumes 0.33 power supply unit loads with 2.8W power dissipation. Intrinsically safe power supplies through the terminal base.

Intrinsic Safety and Electrical Specifications

• This module carries a CENELEC II (1) 2G EEx ia/ib IIB/IIC T4 certification for hazardous area installations. Permissible field values include Uo = 14.5V, Io = 15mA, and Po = 40mW.
• The TC-PIB161 provides galvanic isolation between inputs and the backplane bus. It also isolates inputs from the power supply per DIN EN 50020 standards.
• Inputs share no isolation relative to each other. The module follows NAMUR NE 21 for electromagnetic compatibility requirements.

Fault Detection and Diagnostics

• The module detects lead breakage when input current drops below 0.35mA. Short circuits trigger when current exceeds 6mA.
• Four DIP switches on the bottom of the module enable or disable fault detection. These switches control channel groups 0 to 3, 4 to 7, 8 to 11, and 12 to 15.
• Fault indicators include alarm signals through the backplane bus. A flashing red LED on the affected channel also shows the fault condition.
• Digital filter time is configurable for the entire module. This setting applies uniformly to all 16 input channels.

Environmental and Physical Specifications

• Operating temperature spans –20°C to 70°C with storage capability from –20°C to 100°C. Maximum relative humidity tolerates 95% non-condensing conditions.
• The TC-PIB161 withstands 15g peak shock with 11ms duration. Vibration tolerance meets 2g @ 10Hz to 500Hz per IEC 68-2-6 standards.
• Protection class is IP20, requiring a separate IP54 or better housing for field installations. Dimensions measure 76 x 94 x 46 mm and weight is 0.238 kg.
• Keyswitch position is 6. The module meets EMC compliance through DIN EN 50081-2, DIN EN 50082-2, and NAMUR NE 21 standards.

Frequently Asked Questions (FAQ)

Can the TC-PIB161 accept dry contact switch inputs?

• Yes, the module works with NAMUR sensors and mechanical dry contacts. The 8Vdc quiescent voltage supplies the necessary sensing current.

How does the TC-PIB161 indicate a faulty channel?

• A flashing red LED appears on the affected channel. The module also sends an alarm signal through the backplane bus for system-level diagnostics.

Can I disable fault detection for specific channels?

• Yes, four DIP switches let you enable or disable fault detection per channel group. Each switch controls four channels for flexible configuration.

Is the TC-PIB161 suitable for hazardous area installations?

• Yes, it carries CENELEC II (1) 2G EEx ia/ib IIB/IIC T4 certification. Always follow permissible field circuit values for safe operation.

What is the maximum switching frequency of the TC-PIB161?

• The module supports up to 1kHz switching frequency. This makes it suitable for high-speed counting and position sensing applications.
