DB-24SSRDC 24-ch DC-Type Solid-State Relay Board, 24 Form A Outputs

The DB-24SSRDC/D is a daughter board carrying 24 normally open (FORM A) solid-state relays. Each channel is driven by a 5 V signal applied through the 50-pin header or the 37-pin D-sub connector, so the board can switch high-voltage loads while keeping field wiring electrically separated from the host computer. This helps avoid ground-loop problems and protects the host from damaging voltages.Each relay has an LED that lights when its channel is energised, giving quick visual confirmation of relay status. Field connections are made on screw terminals. The 37-pin D-sub connector allows the board to be driven from any TTL output board, so it can also serve as a general-purpose solid-state relay output stage.This variant is supplied with the CA-3710 cable (DB37 male to male, 45º, 1M), according to the price list description for this code. For the board's operating limits, the contact rating is 4 A @ 3~50VDC and the operating temperature range is 0 ~ 60°C.ApplicationsOn/off controlEnergy managementTest automationProcess control

The DB-24SSR provides 24 Form A solid-state relays on a single daughter board. Each relay is switched by a 5 V signal applied to its channel on the 50-pin header or the 37-pin D-sub connector, so it can be driven directly from a logic output without a mechanical contact.Relay outputs are rated at 4 A at 240 VAC. Because the board isolates the host computer from high-voltage loads and removes ground-loop problems, it suits field wiring of switched AC loads. Twenty-four LEDs show the status of each relay, and screw terminals simplify wiring. Since the 37-pin D-sub connector accepts TTL outputs from other boards, the DB-24SSR can also serve as a general-purpose solid-state relay output board.24 Form A (normally open) solid-state relay channelsRated 4 A at 240 VAC, 0.4 A @ +5 V maximum consumptionSupplied with CA-5015 flat cable, 50-pin, 1.5 mDimensions 130 mm x 220 mm x 32 mm (W x L x H)ApplicationsOn/off controlEnergy managementTest automationProcess control

The DB-24SSR/D is a 24-channel AC-type solid-state relay board for engineers who need to switch field loads from a host computer while keeping the controller isolated from ground loops and high voltages. Each of the 24 Form A channels is energised by a 5 V logic signal applied through the 50-pin header or the 37-pin D-sub connector, and a dedicated LED lights when its relay is active.The 37-pin D-sub connector accepts TTL-level outputs from compatible output boards, so the board can serve as a general-purpose solid-state relay output stage. It also connects directly to OPTO-22 compatible boards. Screw terminals simplify field wiring, and the relays offer long life with no arcing, no bounce and no switching noise.This variant includes the CA-3710 DB37 male-to-male cable (45º, 1 m). The base DB-24SSR ships with the CA-5015 50-pin flat cable instead, so the bundled cable is the main difference between the two codes.ApplicationsOn/off controlEnergy managementTest automationProcess control

DB-24SSR/D/DIN is a 24-channel solid-state relay board for switching AC loads from low-level control signals. Each channel is a Form A (normally open) solid-state relay rated at 4 A @ 240 VAC, and it is energised by a 5 V signal on the matching channel of the 50-pin header or 37-pin D-sub connector.The board is intended for general-purpose relay output duties where a TTL-level output board needs to drive field loads. Its 37-pin D-sub, OPTO-22 compatible and 20-pin connectors give several ways to connect to host hardware, and screw terminals simplify field wiring. A dedicated LED for each relay shows its status at a glance during commissioning and fault finding.This variant is designed for DIN-rail mounting and is supplied with the CA-3710 cable (DB37 male to male, 45°, 1 M). It is rated for an operating temperature of 0 ~ 60°C.ApplicationsOn/off controlEnergy managementTest automationProcess control
