TC-PTBC11 Series C Base Honeywell Intrinsically Safe

Honeywell TC-PTBC11 Terminal Base with Screw Clamps

I/O Capacity & Key Electrical Ratings

• Holds exactly one I/O module per terminal base – mechanically keyed before wiring.
• Intrinsically safe power supply channel: Ui ≤ 10 Vdc, Ii ≤ 2.5 A.
• I/O channel limits: Ui ≤ 30 Vdc, Ii ≤ 100 mA.
• Internal bus (backplane): Ui ≤ 10 Vdc, Ii ≤ 400 mA.
• Capacitance (Ci) ≤ 1 nF for all interfaces; inductance (Li) negligible.

Terminal Layout & Wiring Details

• Total terminals: 52 screw clamps (one row of 16, two rows of 18).
• Power supply terminals: +34, -35, +50, -51 (use +50/-51 for daisy-chaining).
• No-connection terminals: 36 and 49 – leave unconnected.
• I/O assignments depend on the specific module installed – refer to module datasheet.
• Wire cross-section: 0.2 to 2.5 mm² (up to 2 x 1.5 mm² per terminal).
• Terminal screws: M3, compatible with 3.5 mm x 0.5 mm screwdriver.

Environmental & Mechanical Specifications

• Ambient temperature (operation): -20°C to +70°C.
• Storage temperature: -20°C to +100°C.
• Relative humidity: 95% max., non-condensing.
• Pollution gas test: Level G3 per ISA-S71.04-1985.
• Shock: 15g peak, 11 ms duration.
• Vibration: 2g @ 10-500 Hz (IEC 68-2-6).
• Protection class: IP20 (requires IP54 or better enclosure for field installation).

Physical Dimensions & Weight

• Weight: 0.228 kg (0.50 lb).
• Dimensions (H x W x D): 92 x 94 x 94 mm (with module installed).
• Compact footprint saves space in the control cabinet.

Standards & Agency Certifications

• Conforms to DIN EN 50014 (1992), DIN EN 50020 (1997), and DIN EN 50284 (1997).
• EMC compliance: DIN EN 50081-2, DIN EN 50082-2, and NAMUR NE 21.
• CE marked for Europe – requires copper-sealed cabinet and ferrites on power/ControlNet coax.
• ATEX classification: II 2G EEx ia IIC T4 (CENELEC).
• DMT 98 ATEX E 036 U – certified for hazardous areas.

Installation & Mounting

• Mount the TC-PTBC11 on a DIN rail or panel inside a suitable enclosure.
• Install the I/O module after wiring – mechanical keying prevents incorrect insertion.
• Use +50 and -51 terminals to daisy-chain power to adjacent bases.
• Ensure cabinet provides IP54 or better protection for field installation.
• Follow ATEX and EMC guidelines for hazardous area compliance.
