Ver.1.01 CNT16-8(FIT)GY 1 F&eIT Series Isolated Up Counter Module CNT16-8(FIT)GY * Specifications, color and design of the products are subject to change without notice. This product is an expansion module (device module) that up-counts pulse signals input from an external device. The product is used in combination with the I/O controller module < CPU-CAxx(FIT)GY > (*1) or microcontroller unit < CPU-SBxx(FIT)GY > (*1) in the F&eIT Series. Module can count a maximum of eight pulse signals. The pulse signals are input via opto-couplers. The external power supply can be in the range 12 - 24 VDC. *1 The "x" in a model code represents a single digit (or no digit) indicating different products. (The same convention applies below). Performs a 16-bit up-count for eight channels. Isolated from each other by an opto-coupler, offering good noise immunity. A digital filter is included to prevent miscounting due to chattering on the input pulses. A rotary switch allows you to set device IDs to help you keep track of device numbers. Like other F&eIT series products, the module has a 35mm DIN rail mounting mechanism as standard. A connection to a controller module can be effected on a lateral, stack basis in a unique configuration, which permits a simple, smart system configuration without the need for a backplane board. Specifications Item Specification Counter input section Channel count 8 (8 points/common) Counting system Up/down counting Max. count FFFFH (binary data) Response frequency 5kHz (Max.) Duty 50% (Max.) Input format Opto-isolated input (Compatible with both current sinking output and courrent source output) Input resistance 3k Ω Input ON /OFF current 3.4 mA(Min.) / 0.16 mA (Max.) External circuit power supply 12 - 24 VDC (±15%) (4 mA/12 V - 8 mA/24 V per channel) Digital filter 0.25 μsec - 131.072μsec Interrupt The interrupts for all eight channels are combined as a single interrupt output signal. An interrupt is generated when a count carry-up occurs. Common section Interrupt level Using CPU-SBxx(FIT)GY: IRQ 5, 7, or 9 Internal power consumption 5 VDC(±5%) 150 mA (Max.) *1 Allowable distance of signal xtension Approx. 50m (depending on wiring environment) Physical dimensions (mm) 25.2 (W) x 64.7 (D) x 94.0 (H) (exclusive of protrusions) Weight of the module itself 100g Module connection method Stack connection by the connector that is provided with the side of module Module installation method One-touch connection to 35mm DIN rails (standard connection mechanism provided in the system) Applicable wire AWG 28 - 16 Applicable plug FRONT-MC1,5/12-STF-3,81 (made by Phoenix Contact Corp.) *1 The stack connector accepts currents of up to 3.0A (Max.). Installation Environment Requirements Parameter Requirement description Operating temperature 0 - 50 °C Storage temperature -10 - 60 °C Operating humidity 10 - 90%RH (No condensation) Floating dust particles Not to be excessive Corrosive gases None CAUTION When connecting the Module to a controller module, the internal power consumption should be taken into account. If the total current exceeds the capacity of the power supply unit, the integrity of the operation cannot be guaranteed. For further details, please see the Controller Module manual.

Ver.1.01 CNT16-8(FIT)GY 3 The controller module distingui shes and keeps track of the modules that are connected to it by assigning device IDs to them. Each module, therefore, should be assigned a unique ID. A Device ID can be assigned in a 0 - 7 range, so that a maximum of eight modules can be distinguished. The factory setting for the Device ID is [0]. Setup Method A Device ID can be set by turning the rotary switch that is located on the module face. A Device ID can be assigned by turning the switch.
