SAIA PCD1 series programmable controller

Overall positioning and common characteristics of the product

The PCD1 series is a small flat programmable controller launched by SAIA, with a core focus on small scene automation control requirements. It emphasizes high integration, modular expansion, and multi protocol compatibility. The three product lines share the following core commonalities:

Power supply and environment: working voltage 24VDC (± 20%~+25%, including 5% ripple), working temperature 0-55 ℃, protection level IP20, suitable for industrial and civilian control environments;

Basic communication: USB 1.1 (12Mbit/s) and RS-485 (up to 115kbit/s) interfaces are standard, supporting web/IT functions such as FTP, web server, E-Mail, SNMP, etc;

Data backup: Equipped with a replaceable lithium battery (RENATA CR 2032, with a lifespan of 1-3 years) to ensure that data is not lost;

Programming and configuration: Supports PG5 software programming, can print labels through SBC LabelEditor, and provides EPLAN macros for engineering design;

Extended compatibility: Both support PCD7 and W600 analog output modules (0~10V, 12 bit resolution), and can be extended to BACnet, LON IP, and other protocols.

Detailed configuration of each product line

（1） PCD1.M2xxx (Universal Type)

I/O interface details

Input: 6 digital inputs (including 4 normal+2 interrupt, 15~30VDC, 8ms/0.2ms filtering), 2 analog inputs (-10~+10VDC/0~± 20mA/Pt1000, etc., 12 bit resolution);

Output: 4 digital outputs (24VDC/0.5A), 1 PWM output (24VDC/0.2A), 4 configurable I/O (digital input/output), 1 watchdog relay (48VAC/DC, 1A).

scalability

I/O Expansion: Supports PCD2.M5 series I/O modules, which can be expanded to 50 I/O channels through RIO (PCD3. T66x/T76x);

Communication Expansion: Two expansion slots can be used to install PCD2.F2xxx series modules, supporting BACnet MS/TP, LON WORKS, DALI and other protocols, and can expand up to four communication interfaces;

Storage Expansion: Slot M1 can install PCD7.Rxxx module, supporting 4MB~128MB file system expansion, or BACnet/LON IP firmware upgrade.

Typical applications: Control of small and medium-sized automated production lines, upgrading and retrofitting of existing equipment, multi protocol gateways (such as connecting EIB/KNX and M-Bus), and communication interfaces for district heating networks.

（2） PCD1.Room (PCD1.M2110R1, dedicated for room automation)

I/O interface details

Input: 6 digital inputs (including 4 normal+2 interrupt), 6 analog inputs (2 12 bit+4 14 bit, supporting 0~10VDC/0 (4)~20mA/Pt1000, etc.);
