It serves as the physical field wiring interface for the 8C-PDILA1 digital input module, enabling reliable discrete signal collection from proximity switches, pushbuttons, relays, and contact-based field instruments.\u003c\/p\u003e\n\u003ch3\u003eChannel Functionality and Signal Isolation\u003c\/h3\u003e\n\u003cp\u003eThe assembly supports 32 digital input channels operating within a 24 VDC nominal range (18–30 VDC). Channels 1–16 are configurable for pulse accumulation and frequency measurement, while channels 17–32 operate as standard discrete inputs. The system incorporates optical isolation and galvanic isolation rated at 1000 VAC RMS or ±1500 VDC to safeguard control electronics against severe electrical noise.\u003c\/p\u003e\n\u003ch3\u003eElectrical Characteristics and Enclosure\u003c\/h3\u003e\n\u003cp\u003eFeaturing a 9-inch (228.6 mm) compact footprint with conformal coating against airborne contaminants, the unit mounts on standard DIN rails inside control cabinets. It operates across an extended ambient temperature range of –40 deg C to +70 deg C with an input impedance of 4.2 kΩ and an input filter delay of 5 ms ±20%.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e8C-TDILA1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDigital Input Termination Assembly (IOTA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eHoneywell Series 8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible System\u003c\/td\u003e\n\u003ctd\u003eExperion PKS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible I\/O Module\u003c\/td\u003e\n\u003ctd\u003e8C-PDILA1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Allocation\u003c\/td\u003e\n\u003ctd\u003eChannels 1–16 (Pulse\/Frequency), Channels 17–32 (Standard DI)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDI Power Voltage Range\u003c\/td\u003e\n\u003ctd\u003e18–30 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput ON Threshold\u003c\/td\u003e\n\u003ctd\u003e13 VDC min. \/ 3 mA min.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput OFF Threshold\u003c\/td\u003e\n\u003ctd\u003e5 VDC max. \/ 1.2 mA max.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e4.2 kΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Current Rating\u003c\/td\u003e\n\u003ctd\u003e95 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFilter \/ Isolation Delay\u003c\/td\u003e\n\u003ctd\u003e5 ms ±20%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGalvanic Isolation\u003c\/td\u003e\n\u003ctd\u003e1000 VAC RMS \/ ±1500 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoating\u003c\/td\u003e\n\u003ctd\u003eConformal Coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration\u003c\/td\u003e\n\u003ctd\u003eNon-Redundant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIOTA Size\u003c\/td\u003e\n\u003ctd\u003e9 inches (228.6 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN Rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e–40 deg C to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Which digital input module works directly with the 8C-TDILA1 termination assembly?
