☆型号:1747-DPS2 通信模块 电流要求供电
【产品详情】
1747-DPS2 是 Allen-Bradley 通信模块。该模块是一个独立设备,由 24 VDC 的外部电压和 100 mA 的电流要求供电。它主要用于将单个 DF1 连接拆分为两 (2) 个,从而实现多个 DF1 同时连接并支持其他协议。该模块带有多种通信端口,例如它带有一 (1) 个 DF1 控制器端口;一 (1) 个网络 (RS232) 端口;一 (1) 个 Prog / HMI 端口和一 (1) 个可拆卸 RS485 端子。
1747-DPS2 用于 Allen-Bradley 的 PLC、SLC 500 和 MicroLogix 控制器平台。该模块的控制器端口通信是一个 9 针公头 D-shell 端口,具有 19.2 Kbps 或 38.4 Kbps 的自动波特率检测功能,以及自动求和 BCC 或 CRC 检测。支持 RS485 拓扑的网络端口通信是用于 DH-485 的 9 针公头 D 外壳、6 针 Phoenix 式连接器,可配置为 DH-485、DF1 半双工(主或从)、DF1 全双工或 DF1 无线电调制解调器网络。它支持多种通信协议,扩展了 DF1 功能。PROG/HMI 端口是用于 DH-485 的 9 针公 D 外壳、6 针凤凰式连接器,可配置为 DH-485、DF1 半双工(主或从)、DF1 全双工或 DF1 无线电调制解调器网络。
1747-DPS2 支持 DIN 导轨安装。它的工作温度要求为 0-60 oC (32-140 oF);非工作温度为 –40...85 温度 (–40...185 oF),相对湿度为 5 - 95%,无冷凝。它还具有 2 g @10...500 Hz 和 30g 的工作冲击。 Allen-Bradley 的 1747-DPS2 RS-232/DF1 端口分配器是一种电子设备,它将单个 RS-232/DF1 双工通信端口划分为 2 个独立的端口,两个外部设备之间具有并排连接功能。
它有一个直流电源,在 24V DC 时的额定电源为 100 毫安,并提供电路电压隔离。1747-DPS2 通过 9 针公头 D-shell 通信端口连接到控制器,当建立连接时,它会自动将传输速率(波特率)调整为 19.2 Kbps 或 38.4 Kbps(相对于控制器波特率),并最终匹配控制器的 BCC/循环冗余校验和 (CRC)。从控制器发起的传输消息通过 9 针公头 D-shell 网络端口以 19.2 Kbps 的速率接收,但与 1747-DPS1 不同的是,1747-DPS2 的 D-shell 端口可以配置为与 DH-485、DF1 全双工或 DF1 调制解调器网络进行更广泛的通信。

【英文介绍】
1747-DPS2 is the Allen-Bradley communication module. The module is a standalone device powered by an external voltage of 24 VDC and a current requirement of 100 mA. It is primarily used to split a single DF1 connection into two (2), enabling multiple DF1s to be connected simultaneously and supporting other protocols. The module has a variety of communication ports, for example, it has one (1) DF1 controller port; One (1) network (RS232) port; One (1) Prog/HMI port and one (1) removable RS485 terminal.
The 1747-DPS2 is used on Allen-Bradley's PLC, SLC 500, and MicroLogix controller platforms. The controller port communication for this module is a 9-pin male D-shell port with automatic baud rate detection at 19.2 Kbps or 38.4 Kbps, as well as automatic summing BCC or CRC detection. The network port communication that supports the RS485 topology is a 9-pin male D-housing, 6-pin Phoenix connector for DH-485 that can be configured for DH-485, DF1 half-duplex (master or slave), DF1 full duplex, or DF1 radio modem networks. It supports a variety of communication protocols and extends DF1 functionality. The PROG/HMI port is a 9-pin male D housing, 6-pin Phoenix connector for DH-485 that can be configured for DH-485, DF1 half-duplex (master or slave), DF1 full duplex, or DF1 radio modem networks.
The 1747-DPS2 supports DIN rail mounting. Its operating temperature is required to be 0-60 oC (32-140 oF); Non-operating temperature is -40... 85 temperature (-40... 185 oF), the relative humidity is 5-95%, no condensation. It also has 2 g @10... Operating impact of 500 Hz and 30g. Allen-Bradley's 1747-DPS2 RS-232/DF1 port splicer is an electronic device that divides a single RS-232/DF1 duplex communication port into 2 separate ports with side-by-side connectivity between the two external devices.
It has a DC power supply rated at 100 MA at 24V DC and provides circuit voltage isolation. The 1747-DPS2 connects to the controller via a 9-pin male D-shell communication port, and when a connection is established, it automatically adjusts the transfer rate (baud rate) to 19.2 Kbps or 38.4 Kbps (relative to the controller baud rate). And finally match the controller's BCC/ cyclic redundancy checksum (CRC). Transmission messages originating from the controller are received over the 9-pin male D-shell network port at 19.2 Kbps, but unlike the 1747-DPS1, The D-shell port of the 1747-DPS2 can be configured for more extensive communication with DH-485, DF1 full-duplex, or DF1 modem networks.
