DB-24POR/D PhotoMOS Relay Board, 24-ch Form A Relay Output

DB-24POR/D/DIN is a DAQ daughter board that switches 24 FORM A PhotoMOS relay channels, each optically isolated at 5,000 Vdc. It suits engineers who need a compact, solid-state switching stage that can be wired from screw terminals and driven through an OPTO-22 compatible connector.Each channel has an LED that shows its relay status, which simplifies commissioning and fault checking. The board offers three connectors: an OPTO-22 compatible connector, a 37-pin D-sub and a 20-pin connector. This DIN-rail variant ships with a CA-3710 DB37 male-to-male cable, 45º, 1 M.Relay ratings are 130 mA at 350 VAC, with an operate time of 0.7 ms and a release time of 0.05 ms. The board draws 300 mA at 5 V, measures 213 mm x 132 mm and operates from 0 ~ 60°C, with storage from -20 ~ 70°C and humidity of 5% to 90% non-condensing. It is RoHS and WEEE certified.ApplicationsOn/off controlEnergy managementTest automationProcess control

DB-24POR/DIN is a DAQ daughter board that switches 24 channels through optically isolated PhotoMOS relays. Its OPTO-22 compatible connector allows it to be connected to OPTO-22 compatible wiring, and this DIN-rail mounting variant is fitted for DIN-rail installation.Each channel is a FORM A PhotoMOS relay rated at 130 mA @ 350 VAC, with an operate time of 0.7ms and a release time of 0.05ms. LED indicators show the status of each relay, and screw terminals support field wiring. The board draws 300 mA @ 5 V and provides 5,000Vdc optical isolation.This variant includes a CA-5015 flat cable (50-pin, 1.5 M). The board is RoHS and WEEE certified and is rated for an operating temperature of 0 ~ 60°C.ApplicationsOn/off controlEnergy managementTest automationProcess control

The DB-24POR is a daughter board that provides 24 Form A PhotoMOS relay channels for switching loads from a data acquisition system. Each channel is optically isolated, with a rated isolation of 5,000Vdc, which helps keep control-side circuitry separated from the switched side.Field connections are made through screw terminals, and an LED on each channel shows the relay state, which simplifies commissioning and fault finding. The board offers an OPTO-22 compatible connector alongside a 37-pin D-sub and a 20-pin connector, giving several ways to integrate it with a host system.The ordering information for the CR variant includes a CA-5015 flat cable (50-pin, 1.5 m). The board suits on/off switching tasks in energy management, process control and test automation.ApplicationsOn/off controlEnergy managementTest automationProcess control

The DB-24P CR is a 24-channel optically isolated digital input daughter board designed to plug into OPTO-22 compatible digital input cards such as the DIO24, DIO48 and DIO144. Each input uses a bi-directional opto-coupler with a current-sensing resistor, so field signals are electrically separated from the host computer. This separation helps protect the computer against large common-mode voltages, ground loops and voltage spikes common in industrial environments.For DC signals, the board accepts levels from TTL up to 24 V, with an ON voltage level of 2.8 V to 24 V (max) and an OFF voltage level of 1 V (max). For AC signals, the AC filter jumper must be shorted. The input then registers a constant logic high when the AC frequency is 1 kHz or above and the voltage is at least 4 Vrms. Response speed is 20us without filter and 2.2ms with filter.The board draws +5 V at 290 mA and measures 213 mm x 132 mm. It operates from 0 to 60°C and is supplied with a CA-5015 flat cable (50-pin, 1.5 M) for connection.ApplicationsOn/off controlEnergy managementTest automationProcess control
